(6-v)(2v-9)=0

Solution for (6-v)(2v-9)=0 equation:

Simplifying
(6 + -1v)(2v + -9) = 0

Reorder the terms:
(6 + -1v)(-9 + 2v) = 0

Multiply (6 + -1v) * (-9 + 2v)
(6(-9 + 2v) + -1v * (-9 + 2v)) = 0
((-9 * 6 + 2v * 6) + -1v * (-9 + 2v)) = 0
((-54 + 12v) + -1v * (-9 + 2v)) = 0
(-54 + 12v + (-9 * -1v + 2v * -1v)) = 0
(-54 + 12v + (9v + -2v2)) = 0

Combine like terms: 12v + 9v = 21v
(-54 + 21v + -2v2) = 0

Solving
-54 + 21v + -2v2 = 0

Solving for variable 'v'.

Factor a trinomial.

Subproblem 1
Set the factor '(-6 + v)' equal to zero and attempt to solve:

Simplifying
-6 + v = 0

Solving
-6 + v = 0

Move all terms containing v to the left, all other terms to the right.

Add '6' to each side of the equation.
-6 + 6 + v = 0 + 6

Combine like terms: -6 + 6 = 0
0 + v = 0 + 6
v = 0 + 6

Combine like terms: 0 + 6 = 6
v = 6

Simplifying
v = 6
Subproblem 2
Set the factor '(9 + -2v)' equal to zero and attempt to solve:

Simplifying
9 + -2v = 0

Solving
9 + -2v = 0

Move all terms containing v to the left, all other terms to the right.

Add '-9' to each side of the equation.
9 + -9 + -2v = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -2v = 0 + -9
-2v = 0 + -9

Combine like terms: 0 + -9 = -9
-2v = -9

Divide each side by '-2'.
v = 4.5

Simplifying
v = 4.5
Solution
v = {6, 4.5}
